LGTM

People are going to want to iterate over arrays in memory to write simple intrinsic loops.  If we don't allow `p + i` to work, people will be forced to write `(__SVInt8_t*)((char*)p + i * svcntb())`.  Which is the same thing, just a lot uglier.  And it wouldn't really be that crazy to support `sizeof(__SVInt8_t)`.  I mean, it's effectively just a different way of spelling `svcntb()`.  I guess we can always relax it later, though.
